Volvo service fixed my buzzing (in 2nd, 4th and 6th gears) shifter today. On the 15-minute ride home, the shifter did not buzz. (I also thought the shifter felt more precise, but maybe that was just my subjective impression.) I thought you might be interested in the description of the work:
"Tech found shifter cables loose within shifter assembly. Removed air cleaner box. Removed center console side and dash panels. Removed shifter assembly. Replaced shifter cables assembly. Adjusted cables. Test drove. Okay."
